Advantages for professional activities and for the ecosystem. The new “E20” forestry head for excavators, recently presented by Seppi at Intermat 2024 held in Paris from April 24 to 27, offers dual benefits. The design focus of the technicians from the Trentino-based brand when creating the new equipment was to maximize the functional efficiency of the head in the most demanding agricultural and forestry applications, while also improving environmental sustainability throughout the machine’s entire operational lifecycle.
Maximized efficiency and improved reliability
In this context, the new “E20” is made using high-strength materials that ensure the equipment’s longevity even with daily use in the most challenging applications. Specifically, the “Ar400” steel used for the machine body allows it to work without issues and with reduced energy absorption even in the presence of stones and other foreign materials on the ground, shredding thick vegetation, shrubs, trees, and stumps up to 20 centimeters in diameter. This is largely thanks to the real innovation proposed by the “E20”: a next-generation patented rotor incorporating fixed “Mini Duo” and “Mini Extreme” tools reinforced with tungsten carbide inserts, directly coupled to a hydraulic transmission called “Direct Drive,” partially integrated into the rotor itself, ensuring dual benefits.
On one hand, this ensures a constant transmission of torque due to a 50 percent reduction in power losses caused by friction. On the other hand, it allowed Seppi technicians to eliminate traditional wear components, such as pulleys and V-belts, thus eliminating the risk of failures caused by potential overloads or breakages. This results in greater efficiency during applications in the most demanding fields with lower energy consumption and consequently reduced fuel consumption for excavators weighing between 12 and 21 tons, for which the “E20” forestry head is specifically designed.
Furthermore, the rotor’s capacity to support high lateral loads contributes significantly to this objective, enabling it to work effectively even in a vertical position. This is also aided by the presence of a variable displacement hydraulic motor called “M-Boost,” which ensures automatic pressure variation by adjusting displacement based on the power demand of the ongoing task. This capability is particularly emphasized when the rotor is equipped with the “Cut Control” system, which includes depth limiters.
